Book Talk: Does proportionality analysis promote judicial activism?

Proportionality analysis enjoys increasing popularity among constitutional courts as a tool of fundamental rights review. However, critics claim that proportionality analysis affords too much discretion to judges and is thus an instrument for judicial activism.

In his recent monograph, Proportionality and Judicial Activism: Fundamental Rights Adjudication in Canada, Germany, and South Africa (Cambridge University Press, 2017), Niels Petersen tests this argument empirically. The book presents the results of an empirical analysis of the fundamental rights jurisprudence of three apex courts – the Canadian Supreme Court, the German Federal Constitutional Court and the South African Constitutional Court. It argues that the core of the normative critique is correct: proportionality analysis indeed gives judges a large degree of discretion. However, this does not automatically lead to judicial activism. Instead, the empirical analysis shows that courts exercise considerable self-restraint when applying the proportionality test.

Furthermore, Niels was a Visiting Doctoral Researcher (2006/07) and a Hauser Research Scholar (2012/13) at the New York University School of Law. His research focuses on comparative constitutional law, human rights law, the sources of public international law as well as the economic analysis of law.
